Novel cold-mixed and cold-laid wearing layer emulsified asphalt mixture and application method thereof
The invention discloses a novel cold-mixed and cold-laid wearing layer emulsified asphalt mixture and an application method thereof, and the novel cold-mixed and cold-laid wearing layer emulsified asphalt mixture comprises the following components in parts by mass: 500-800 parts of coarse aggregate, 200-500 parts of fine aggregate, 70-160 parts of rosin resin composite modified emulsified asphalt, 0.1-10 parts of cement, 0.1-12 parts of external seepage water and 0.1-2 parts of an external seepage water modifier, the rosin resin composite modified emulsified asphalt is prepared by mixing a linear or star-shaped SBS modifier, 210 rosin modified phenolic resin and emulsified asphalt. According to the invention, rosin resin composite modified emulsified asphalt is introduced, and aggregate gradation and the construction process are improved, so that the obtained novel cold-mixed and cold-laid wearing layer emulsified asphalt mixture can achieve pavement performance of the hot-mixed ultrathin wearing layer after being laid, the problem of poor pavement performance of the traditional cold-mixed process is solved, and the mixture has the advantages of convenience and excellent performance at the same time.
本发明公开了一种新型冷拌冷铺磨耗层乳化沥青混合料及其应用方法，以质量份数计，该新型冷拌冷铺磨耗层乳化沥青混合料包括以下组分：粗集料500～800份，细集料200～500份，松香树脂复合改性乳化沥青70～160份，水泥0.1～10份，外渗水0.1～12份和外渗水改性剂0.1～2份；所述松香树脂复合改性乳化沥青由线型或星型的SBS改性剂、210松香改性酚醛树脂与乳化沥青混合制成。本发明通过引入松香树脂复合改性乳化沥青，同时改进集料级配和施工工艺，使所得到的新型冷拌冷铺磨耗层乳化沥青混合料铺设后能够达到与热拌超薄磨耗层的路用性能，解决了传统冷拌工艺路用性能不佳的问题，使其同时具备了便捷性与优异性能两方面优势。
